An admin is troubleshooting a config error. They run `nginx -t` and it fails. They fix the error and want to apply the fix. What is the safest next step?

Run `nginx -t` again to apply the fix.

Run `nginx -s stop` and start NGINX.

Run `nginx -s quit` and start NGINX.

Run `nginx -s reload` to apply the fix.

In which scenario is a stop/start more appropriate than a reload?

Changing the log format directive

Updating an SSL certificate file

Applying a new server block configuration

Troubleshooting a hung worker process that is not responding to reload signals

Which statement accurately describes the process behavior during an NGINX reload?

All worker processes are terminated immediately, and new ones are started.

New worker processes are started, and old workers are shut down after finishing their current tasks.

Only the configuration file is re-read; no processes are affected.

The master process stops and a new master process is started.

An admin updates the `worker_processes` directive in nginx.conf from 2 to 4 and runs `nginx -s reload`. The site is serving live production traffic. What is the immediate effect on active client connections?

All active connections are terminated immediately, and new connections are handled by 4 workers.

The master process restarts, causing all workers to be recreated and all connections to drop.

Active connections are paused briefly while the master process re-reads the config, then resume on the new workers.

Existing connections continue with the old workers, and new connections are handled by the new 4-worker pool.
